WILLIAM COX, OF HAMILTON, ONTARIO, CANADA DISINTEGRATOR.

Specification of Letters Patent.

' Patented Jur 30,1907.

Application filed July 14:, 1906. $erial No. 326,231.

To all whom it may concern: I

Be it known that 1, WILLIAM Cox, a subject of the King of Great Britain,and a resident of Hamilton, in the county of Wentworth and Province ofOntario, Canada, have invented new and useful Improvements inDisintegrators, of which the following is a specification.

My invention relates to improvements in disintegrators in which twostationary rings a distance apart from each other have a circle oftransverse bars placed at an angle and in relative position with therings and secured therein. The rings are placed in a stationary casing,and a beater disk suitably mounted in the casing and adapted to revolvetherein and the heaters on the disk in proximity to the inner parts ofthe transverse bars for disintegrating purposes.

The objects of my invention are first, to provide a disintegrator withscreen bars adapted to grind products such as spice, roots, barks,leaves and seeds of various kinds to a granular form. Second, to providea disintegrator with said screen bars adapted to grind products to aless granular form, third, to provide screen bars of a form and designto allow the disintegrated and granular material to immediately dropfrom the angle of the bars and direct through the openings or passagesbetween the bars, fourth, to provide stationary bars of a form anddesign to allow the product to be ground and reground on account of theground material finding a rebounding surface on the bars and fifth, toafford a more indirect passage through the bars to produce a lessgranular material. I attain these objects by the mechanism illustratedin the accompanying drawing, in which Figure 1 is a sectional elevationof the disintegrator showing the ring of screen bars in position in astationary casing, and a beater disk mounted on a shaft in the casingand adapted to revolve in either direction and in proximity with theinner sides of the bars, a part of the disk broken therefrom to show theopening in the rear of the casing for the entrance of the material to bedisintegrated. Fig. 2 is an enlarged sectional elevation of a segment ofthe ring with a number of the screen bars. Fig. 3 is a plan of Fig. 2 ofthe drawing, two of the bars being removed to show the brace-rods whichfasten the ring plates together.

Similar letters refer to similar parts throughout the several views.

In the drawing A is a stationary casing of suitable design and shape, Band B are ring plates secured together by means of a number ofbrace-rods G, and secured in the central part of the casing A. A centralshaft D, is suitably mounted and passes through the casing, and on theshaft is mounted a disk E which is adapted to revolve in eitherdirection together with the shaft. On the disk and in suitable placesare a number of steel beaters F to operate in proximity with the innersides of the circle of transverse screen bars H, which extend throughthe rings B, and flush therewith and are secured thereto. J, is a holethrough the rear side of the casing to admit material to bedisintegrated.

All the above indicated parts of the disintegrator, excepting the screenbars H, are not new, nor do I claim the same, see my United StatesPatents 769,253, Sept. 6th. 1904:, and 794,785, July 18th. 1905.

The circle of screen bars H, as formed and placed in the rings B, are ofthe same angular form, and a distance apart and proportionate to eachother, and also to the rings, these are the features of the invention.

When the disk E with beaters revolve in the direction indicated byarrow, in Fig. 1 of the drawing, the material is forced against thebreaking and cutting edges 2, of the bars H, and said material whenbroken, and granular, falls by gravity, through the direct openings 3,between the bars H. It will be noticed that the cutting and breakingedges 2, are formed with considerable wearing surface.

When the disk is revolved in an opposite direction the material isforced by the boaters against the less inclined face I, of the bars H todisintegrate the material and said material finds a temporary lodgmenton the inclined surface 4 and 5 of the bars and more particularly on thesurface 4, thereby becoming less granular and more of the nature offlour previous to its fall through the now indirect openings 3, betweenthe bars. The

rebounding surfaces 4, of the bars also present a large wearing surfacesimilar to the wearing surface 2 previously referred to. It will also benoticed that immediately the disintegrated material has passed throughthe openings 3, that said openings widen out very extensively and allowthe material to freely pass through said openings by the fact of theparts 6 and 7 of the bars receding from each other, thereby preventingany possible clogging of the disintegrated material. The flat part 8 ofthe bars allow the large wearing surfaces 2 and 4 referred to, and theopposite part of the bars have a similar, but smaller flat wearingsurface 9 to allow wear on the surface 5 for a length of time before anacute angle is produced by the inclined surface 5 and the part 7 of thebars.

The bars H are made of hardened steel to more fully endure the wear andtear of the disintegrating process.

The operation ofthe disintegrator is as follows'.- The material to bedisintegrated is passed through an opening .I, in a convenient place inthe casing, and allowed to fall on the bars H at the same time that thebeater disk is revolving as indicated by arrow, to disintegrate thematerial against the parts 2 of the bars. When disintegrated thematerial falls through the direct openings 3 as shown in Fig. 2 of thedrawing, and then through the lower opening in the casing and into anyreceptacle placed in desired position.

In order to disintegrate similar or other material to a less granularproduct, the disk beater together with its central shaft D is revolvedin an opposite direction to that indicated by arrow, and the material isforced against the rebounding surfaces 4 and 5 of the bars H, previousto passing through thenow indirect openings 3, thence downward bygravity, to any desired re ceptacle.

i In disintegrating material to produce less granular products the sameresult would be obtained by reversing the circle of barsH.

What I claim as my invention and desire to secure by Letters Patent, is:

A disintegrator' comprising ,a stationary casing, ring plates oppositeto each other secured therein,'transverse bars of similar angular formsupported by the ring plates an equal distance apart, two breakingsurfaces on each of said bars at right angles to each other; one of saidsurfaces being plane, the other having an obtuse-angled depressiontherein, and rotary heaters coacting with said breaking surfaces toproduce a fine or coarse pulverization according to the direction ofrotation of said heaters.
